1. The problem statement, all variables and given/known data A hockey puck is sliding across a frozen pond with an initial speed of 7.5 m/s. It comes to rest after sliding a distance of 23.7 m. What is the coefficient of kinetic friction between the puck and the ice? v0x = initial speed = 7.5 m/s vfx = final speed = 0 m/s Δx = x distance traveled = 23.7 m fk,IP = force of kinetic friction from ice on puck NIP = normal force from ice on puck WEP = weight force from earth on puck mP = mass of puck g = acceleration due to gravity 2. Relevant equations ƩFnet = m*a ƩFx = -fk,IP = m*ax ƩFy = NIP - WEP = m*ay → ay = 0 m/s^2 → NIP = mP*g 3. The attempt at a solution I attempted this logic... fk,IP = μk*NIP → (-m*ax)/(mP*g) = μk But then I hit a wall when trying to find the x-acceleration. Help?
